NELSON SMITH, OF BELLEVILLE, NEW YORK.

CHURN.

SPECIFICATION forming part of Letters Patent No. 269,129, dated December 12, 18 Application filed September 6, 1882. (No model.)

To all whom it may concern Be it known that I, NELSON SMITH, aicitizen of the United States, residing at Belleville, in the county of Jefferson and State of New York, have invented certain new and. useful Improvements in Ghurns, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improvement in churns; and it consists in combining with a rotating-bod y churn an oppositely-rotating series of paddle-dashers of peculiar construction ournaled therein; and it further consists in providing the churn and paddles with suitable gearing, whereby the opposite rotation of the churn and itsinteriorly-revolving paddles is caused, as will be more fully set forth hereinafter.

In the accompanying drawings, Figure 1 is a perspective view of my invention. Fig. 2 is a vertical cross-section of the same. Fig. 3 is a vertical longitudinal section. Figs. 4 and 5 are detailed views of my improved paddles.

A represents the barrel or body of the churn,

octagonal in cross-section. It is mounted between the standards 0 by means of flanged sleeves b, secured centrally to its ends by m ea us of bolt a, as shown. The shaft B, upon which is mounted the agitators, is journaled in and projects through one of them, preferably the left-hand sleeve. This sleeve is provided with a miter-gear, c. The opposite end of the shaft is journaled, in any ordinary manner,in the opposite sleeve. This portion of the machine, however, is not shown in the drawings. This miter-wheel c meshes in with the horizontal miter-wheel d, journaled upon the shaft 0, which issecured to the bracketf, made fast to the standard 0, and into the miter-wheel c, vertical miter-wheel g, which is rigidlysecured to the shaft B. To the outer end of the shaft B is attached the crank it, by means of the gearing above described. The shaft and churn-barrel are made to rotate in opposite directions. Secured to the'shatt B, inside the churn-barrel, are the radial paddles D, which have the. slots 112 out in them at proper intervals, from which slots projecttheinclined slats n, which are beveled toward a point, as at o, in which slats are perforations 10. These slats project alternately from opposite sides of the paddles D.

in operation, as the paddles revolve, the slats, which project in the direction of the movement, will act as wedges and violently separate the cream, which will be thrown into the open sides of the intervening slats, and'as violently compressed by the inclined slats, escape'being only allowed through the perforations p and the space 0 between their outer,

edges. By this construction a very thorough agitation of the contents of the churn willbe secured, as will be readily understood. The barrel A is provided with an opening, 1', upon one of'its sides, which opening may be closed by means of the cover k, provided with any suitable locking device, l.

A churn thus constructed will be foundvery efficient, cheap, and simple, and will not be l them, and having projecting from the sides of said recesses converging perforated slats, said slats being arrangedto project alternately from opposite sides of their respective paddles, as shown and described.

In testimony whereof I atfix my signature in presence of two witnesses.
